将现有字段添加到新屏幕

Question

我正在尝试将采购订单屏幕的OrderNbr和OrderType字段添加到新创建的屏幕。

我在OrderType选择器的屏幕上看到视图不存在错误。附加了与屏幕关联的图形和DAC

    public PXSave<PONextAction> Save;
    public PXCancel<PONextAction> Cancel;        
    public PXFilter<PONextAction> MasterView;

    [PXProjection(typeof(Select<POOrder>), Persistent = true)]
    [Serializable]
    public partial class PONextAction : IBqlTable
    {
        #region OrderType
        public abstract class orderType : PX.Data.IBqlField
        {
        }
        protected String _OrderType;
        [PXDBString(2, IsKey = true, IsFixed = true, BqlField = typeof(POOrder.orderType))]
        [PXDefault()]
        [PXUIField(DisplayName = "PO Type", Enabled = true)]
        [PX.Objects.PO.POOrderType.List()]
        public virtual String OrderType
        {
            get
            {
                return this._OrderType;
            }
            set
            {
                this._OrderType = value;
            }
        }
        #endregion
        #region OrderNbr
        public abstract class orderNbr : PX.Data.IBqlField
        {
        }
        protected String _OrderNbr;
        [PXDBString(15, IsUnicode = true, IsKey = true, InputMask = "", BqlField = typeof(POOrder.orderNbr))]
        [PXDefault()]
        [PXUIField(DisplayName = "PO Nbr.", Enabled = true)]
        [PXSelector(typeof(Search<POOrder.orderNbr, Where<POOrder.orderType, Equal<Current<POLinePM.orderType>>>>), DescriptionField = typeof(POOrder.orderDesc))]
        public virtual String OrderNbr
        {
            get
            {
                return this._OrderNbr;
            }
            set
            {
                this._OrderNbr = value;
            }
        }
        #endregion

    }

Answer 1

您似乎复制了POOrderR Alias DAC模式。别名DAC通常在需要同时将同一DAC的两个当前对象存储在内存中时使用。

您的用例不需要这样做。不要创建新的DAC，请重复使用POOrder DAC（而不是POOrder R ）。我不确定为什么要创建一个新的DAC，也许是为了避免在其他地方显示自定义字段？如果是这种情况，您可以改为查看“可见性/可见性”属性。
